VENTILATOR.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application filed March 16, 1910. Serial No. 549,658.

To all whom it may concern:

Be it known that I, EDWARD STEPHANY, a citizen of the United States ofAmerica, residing at Rochester, in the county of Monroe and State of NewYork, have invented new and useful Improvements in Ventilators, of whichthe following is a specification.

This invention relates to ventilators, and it has for its object toproduce a simple and eflicient ventilating device which may beeffectively used in connection with the windows of houses, railroad carsand the like and for various other purposes.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawing,-Figure 1 is an elevation of a portion of a window frameshowing the ventilating device applied in position for operation. Fig. 2is a top plan view, showing the ventilating device removed from thewindow frame. Fig. 3 is a sectional view, enlarged, taken on the planeindicated by the line 3-3 in Fig. 1.

Corresponding parts in the several figures are denoted by likecharacters of reference.

Referring to the drawing, 1 designates a sleeve or casing which may becylindrical, as shown in the drawing, or it may be of any desiredcontour in cross section. Said sleeve or casing is provided adjacent toone end, which, for convenience will be designated the inner end, with across bar 2 having an eye or opening surrounded by a sleeve or collar 3in which a stem 4 is longitudinally slidable, said stem carrying at oneend a limiting nut or stop 5 and at the other end a hood 6 whichconstitutes a closure for the inner end of the casing 1, said hood orcap having an offset 7 affording the seat for the inner end of thecasing which may thus be tightly closed or obstructed. The hood or cap 6is of such dimensions that it will form a flange 8 extending orprojecting circumferentially around the casing 1. A knob or handle 9 isprovided, the same having threaded connection with a reduced portion ofthe stem 4: which extends through the hood or cap 6.

The outer end of the casing 1 is obstructed by a strainer 10 formed offine wire net ting or other suitable material, said strainer beingpreferably seated upon a beveled portion forming an inturned flange 11at the outer end of the casing where, if desired, it may besecured bysolder or other suitable means, although this is not essential. A stopbead 12 is formed circumferentially upon the casing 1 adjacent to thebeveled portion and upon which the strainer is seated.

A baseboard 13 is provided with an opening 14: of appropriate shape toreceive the outer extremity of the casing including the beveled portion11 and the bead 12, the portion of the strainer which is in engagementwith the beveled portion 11 being clamped between the latter and thebaseboard, as will be clearly seen in Fig. 3. It will be readily seenthat the strainer member being thus securely held and clamped, there isno urgent necessity for independently securing the same upon thestrainer casing, the construction shown enabling the strainer to beremoved and conveniently renewed when desired. An annular washer member15 surrounding the casing and secured upon the baseboard 13 by fasteningmeans such as screws 16 engages the head 12, thus securing the casingfirmly upon the baseboard. A

In the form of the invention illustrated in Figs. 1 and 2, twobaseboards here designated 17 have been connected together by means ofhinges 18, said baseboards being provided at their meeting edges withinterengaging flanges 19 to form a tight joint. A ventilator casing l ofthe construction shown in Fig. 3 has been mounted upon each baseboard17. By this construction the improved ventilating device may be readilyapplied to an ordinary window frame below the bottom sash, the ends ofthe baseboards being readily inserted between the stop beads, thusaffording a ventilating device which may be readily placed in positionor removed when desired and which is especially applicable to thewindows of houses, railroad cars and the like. A baseboard, however, maybe permanently connected with the window frame or casing, said baseboardcarrying one or more ventilators, as may be desired. Again, the improvedventilator may be applied directly to the wall of a house or otherstructure, such wall being regarded constituting the baseboard uponwhich the ventilator casing is mounted, substantially as shown in Fig.3.

From the foregoing description, taken in connection with the drawinghereto annexed, the operation and advantages of this invention will bereadily understood. By simply pulling the stem l carrying the hood orcap 6 in a forward direction, the air entering through the strainer willbe deflected against 15 the hood or cap and will thus enter theapartment or car with which the device is connected without possibilityof creating an unpleasant draft. The amount of ventilation may bereadily regulated by the position of the hood or cap, and the device issimple, efficient and inexpensive.

Having thus described the invention, what is claimed as new, is

In a ventilating device, a baseboard having an opening, a casing havinga beveled end and a stop bead engaging the opening, a strainer clampedbetween the casing and the baseboard, an annular washer secured upon thebaseboard in engagement with the bead of the casing to retain thelatter, and a slidably supported hood or cap to obstruct the inner endof the casing.

In testimony whereof I aflix my signature in presence of two Witnesses.
